摘　　要：随着可再生能源在配电网中接入比例不断的增加,主动配电网的发展适应了分布式电源接入的控制与管理。为了使分布式电源的增加适应配电网扩展规划要求,文章提出分层一致性主动控制的方法对配电网负荷变化时的分布式电源进行协调控制,每一控制目标只需和邻近目标交互局部信息,在没有全局性信息的场景下实现全局最优一致性控制。该方法首先对分布式电源节点进行分层分类,通过对全局主电源节点及各层的电源节点的监控,结合局部电源间的信息通信实现最终一致性的目标。最后通过IEEE26节点算例证明了分层一致性控制在主动配电网中应用的可行性和正确性。With the increasing renewable energy resources in the distribution network, the development of active distribution network has adapted to the control and management of distributed generation. To make sure the increase of distributed power can adapt to the expansion planning requirements of distribution network, this paper presents an active control method of hierarchical consistency to control distributed generation. When the load changes, each control objective just needs to interact related information with the neighboring objects, and it can achieve the goal of global optimum consistency control without global information. The method classif ies the distributed generation node at f irst, and achieves the ultimate goal of consistency based on the information of local distributed generation by monitoring the power of main distributed generation node and other distributed generation nodes in each layer. The application feasibility and correctness of hierarchical consistency control in active distribution network are validated by IEEE 26 node case.
